Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If heat is generated by applying current to an electric wire, then heat generation capability is improved, but safety deteriorates due to exposure risk to human body
Solution Approach 1:
The patent introduces an induction patch as an intermediary device that generates a magnetic field to wirelessly transmit power to the heating element. This eliminates direct electrical contact between the power source and the heating element, thereby removing the safety hazard of exposed currents while maintaining effective heat generation capability
Solution Approach 2:
The patent replaces the traditional mechanical electrical connection system with a wireless electromagnetic induction system. The induction patch and heating element use magnetic coupling to transfer energy without physical contact, substituting the mechanical wiring system with a field-based energy transmission mechanism that inherently provides electrical isolation and safety
2Use of energy by moving object
If traditional contact-based charging is used, then power transfer efficiency is improved, but user convenience deteriorates due to contact requirements
Solution Approach 1:
The induction patch serves as a wireless power transfer intermediary that enables contactless charging through magnetic field coupling. This allows the heating element to receive power without physical contact, significantly improving user convenience while maintaining efficient energy transfer through optimized magnetic coupling design
3Temperature
If conductive metal yarns are woven into fabric heating element, then heat transfer to user is improved, but manufacturing complexity deteriorates
